Abstract: The present invention relates to a method for reducing localized fat deposits in a subject in need thereof in need thereof by topically treating the subject with rare-earth element doped calcium carbonate particles in combination with low-intensity ultrasound. The rare-earth element doped calcium carbonate particles have good biocompatibility and can increase reactive oxygen species (ROS) production and produce carbon dioxide (CO2) and calcium ions (Ca2+) in the region of administration under the ultrasonic irradiation. The method of the present invention is effective in inducing adipocyte necrosis, inhibiting adipogenesis, and decreasing body weight and useful for body sculpture.

Abstract: A water lubrication screw type air compressor includes a compressor, an air-loop system and a water-loop system. The water-loop system includes a water supply device, a first water-loop unit and a second water-loop unit. The water supply device includes a first water-treatment device to modify the water quality and provide purified water. The first water-loop unit includes a second water-treatment device to modify water quality and reduce the corrosion of metal components. The second water-loop unit includes a water filter to remove the impurities in water and maintain the purity of cycling water. Therefore, the water-loop system in the present disclosure includes multiple water-treatment devices and filters to maintain the water quality. The purified water ensures better cooling, lubrication and air proofing when injected into the compressor.

Abstract: A water lubrication air compression system disposes an lubricant heat dissipation system at a bearing chamber close to the high pressure end of the compressor for cooling and circulating lubricant due to the rise of temperature during operation of the compressor, hence enhancing the ability and stability of the compressor. On the other hand, a negative pressure system is connected to the air chambers between the oil lubrication and the water lubrication of the compressor in order to provide a negative pressure. If any leak of water vapor at the compressor chamber or oil vapor at the bearing chamber, the negative pressure system is able to produce a negative pressured condition toward the sealing structure so that the oil lubrication can be effectively isolated from the water lubrication and inter-contamination between the lubricant and water can be avoided.
